LINCOLN, Neb. (AP) — A 45-year-old Lincoln man accused of killing his roommate has pleaded not guilty to first-degree murder.

Trenton Reiner appeared by video from the jail Wednesday for the arraignment in Lancaster County District Court.

Police say Reiner killed 35-year-old Robert Leazer sometime after May 7 in the mobile home they shared. An autopsy showed Leazer died of blunt-force trauma to the head.

Police were called to the Contempo Lincoln Mobile Home Park on May 26 to check on reports that Trenton Reiner was breaking the windows of his car. Officers found Leazer’s decomposing body inside the home.
